To all whom it may concern:

Be it known that CHARLES J GADD, deceased, formerly a citizen of the United States, residing at Lebanon, in the county of Lebanon, State of Pennsylvania, did invent a certain new and useful Anticreeper for Rails, of which the following is a specification. y;

The inventionrelates to anti-creepers'for railway rails of the general character indicated in Patent N 0. 1,116,686 for rail anchor, patented October 10,1914.

The purpose of the invention-is to limit the movement of the relatively fixed and movable clamp members with respect to each other. i

A further purpose is to reduce the danger of accidental release by causing themovable clamp member to be engaged by the fixed clamp member upon but slight release movement of the one with respect to the other.

A further purpose is, in connection w th a clamp member rolling at its inner side upon an abutment carried by another clamp member, to provide an edge upon the fixed member to engage the outer side of the movable member to limit the rolling movement.

It is desirable to provide two suchedges on opposite sides from the center line through the rolling abutment and the fixed clamp member. 1 A

A further purpose is to adjust one member of a two-part anti-creeperlongitudinally through the other but to also cause them to engage angularly so as to turn the anticreeper angularly in its entirety wlth respect to the rail length.

Further purposes will appear in the specification and in the claims thereof.

It is preferred to illustrate the invention by but one form thereof, selecting a form which has proved to be practical, efficient, and inexpensive and which at the same time well illustrates the principles of the in:

vention. n

Figure 1 is a top plan view showing the I anti-creeper in position of use, the rail and tie being dotted in. r Fig. 2 is an end elevation of the anti creeper in position, a POI'tIOII'Of the rail being dotted in.

Figs; 3 and 4-are perspective views of the relatively fixed and -movable clampimemhers, respectively, of the anti-creeper.

Fig. 5 is a top plan view showing the 7 parts as initially assembled, preparatory to placing them in position beneath the rail.

Similar numerals indicate like parts in the specification.

The anti-creeper comprises two parts 11 and 12, which for convenience are referred to herein as the fixed and movable clamp members respectively, because, as between them, the part 12 moves through the rela tively fixed part 11. Both parts are moved both longitudinally and angularly with re spect to the rail.

The fixed member 11 carries a rail clamp 13 at one end, formed between the body 14 of the member and a reversely turned terminal '15. Thismember is shown as engaging the flange 16 of the rail andas extending in adirection nearly across the rail length in the position of use in Fig. 1.

The body 14 lies beneath the rail and is provided near the end farthest from the clamp with a vertical transverse slot or groove at 17, whose walls present, respectively, a preferably central curved surface 18 intended to act as an abutment, ashereinafter indicated and at least one, preferably two gripping edges, or dogs, 19, and 20. Each of these most desirably lies outside of the medial plane through the length of the body,or through the abutment, if it be not central, and where-two are used they lie on opposite sides of this plane. They may be located at diiferentheights as shown. This construction is conveniently secured by partly shearing the body 14 longitudinally in a horizontal direction as at 21 and 22, turning the two ends 23 and 24, thus separated in opposite directions to present theiropposite edges for the purpose indicated. V

Each of these dogs 19 and 20 is useful and they are useful in combination, but either may be furnished without the other with part of the advantage of the invention.

It'will be seen that this portion of the invention differs from said prior patent above named inthe provision of these biting surfaces or dogs in proximity to the abutment 18, whereas in said patent the abutment corresponding to 18 is considerably spaced from the nearest metal in the direction of the length of the body 14;

The second member 12 is comparable with the second member shown in the patent. It comprises a terminal clamp 25 between its body 26 and the reversely turned end 27, so as to clamp the other rail flange, 28 between them. The body 26 provides an intermediate curved portion 29 adapted to lie within the slot 17, and also a terminal tieengaging arm 30.

When the parts are fitted together this second or movable clamp member 12 is placed with the curved portion 29 in slot 17 so that the interior curved surface 31 will roll upon the abutment face 18. The slot 17' is given just sufficient width between the abutment and the dogs 19 and 20 to permit a slight rocking action of member 12 about the abutment 18. At each extremity of the rocking action,. where two of the dogs, 19 and 20 are provided, some portion of the outer surface 32 of the member 12 comes in contact with one or other of the dogs limiting the rocking movement and, for further movement of the member 12, carries the member 11 with it angularly, usually about the flange 16 as a center.

Where the advantage of but one of these dogs, 19 or 20 is sought it will be obvious that the other may be omitted, with the result that rolling of member 12 about the abutment 18 of member 11 i thus limited in one direction only.

In setting up the two parts of the clamp the member 12 is placed in position within the slot 17 but with the parts in some such relation as is seen in Fig. 5, permitting the member 11 to be passed beneath the rail and brought into engagement with the flange 16, as seen in Figs. 1 and 2 after which the member 12 is moved longitudinally through the slot 17 until its clamp 25 engages flange- 28 of the rail. may be fed its entire length through slot 17 after the member 11 has been put in position, if desired. 7

The member 12 is passed as far through the slot in an upward and clockwise direction as can conveniently be done until the clamps terminating the two members engage the rail. The anti-creeper is then driven bodily along the rail the remaining distance required until the arm 30 comes in contact with the next adjoining tie, at which time longitudinal movement of the clamp upon member 12 temporarily ceases. The clamp terminal of member 11 is then driven still farther along the flange toward the tie, causing the dog 19 to grip the member 12 and resulting in a turning action upon the member 12 bringing clamp 25 tightly against the rail flange 28. This tends to release the arm 30 somewhat from the tie. Both of the terminal clamps may then be driven along the rail somewhat farther until the angular position of the entire anti-creeper with respect to the direct transverse line across the rail Of course, the member 12 gives the required strength of clamping action upon the two rail flanges at the same time that the arm 30 tightly engages'the tie. Preparatory to the setting up of the parts some longitudinal driving of the clamp as an entirety along the rall may be avoided and the anti-creeper may at the same time be set a little if the movable clamp member be driven through the fixed clamp member to eifect more quarely across the rail the clamping action. 1

The two edges 19 and 20 prevent any extended movement of the members 11 and 12 with respect to each other and under the varying. circumstances of use, the edges 19 and 20 prevent loosening in one direction or the other. 7

Having thus described the invention, what is claimed as new and desired to secure by Letters Patent is: 1

- 1.. In an anti-creeper, a member having a vertical slot, a clamp at one end, a body portion passing beneath the rail, an abutment upon one side of the slot, a dog upon the opposite side of the slot, a second member adapted to enter the sot and there curved and engaging the abutment and adapted in rolling about the abutment to engage the dog, limiting angular movement, in combination with a flange engaging clamp upon one end of the second member and a tie engaging arm on the opposite end thereof- 2. In an anti-creeping device for rails a member having a rail-fiange-engaging clamp at one end and an abutment at the other, an eccentrically placed dog spaced from the abutment and a second member having a rail-flange-engaging clamp at one end and a tie engagingarm at the other, bent between these ends-there passing through the passage to roll about the abutment and engage with the dog. 1

3. In an anti-creeper for rails, a member provided with a rail-flange-engaging clamp at one end and an abutment at the other end in combination with a plurality of dogs upon the member spaced from the abutment and having engaging edges on opposite sides of the center line joining the clamp and abutment, and a second member passing between the abutment and dogs and curved about the abutment to carry a flange engaging clamp on one end and a tie engaging arm on the other.

4. An anticreeping device comprising a member having a rail engaging clamp at one end and providing a restricted passage at the other in combination with a'second member passing through the restricted passage and having a rail engaging camp at one end and a tie engaging arm at the other.
